Dr. Sarah's Sampling Exercise

Stations and Desired Percentages

percentage of red chips in the blue seethrough
glass with blue and red chips

percentage of white dice in the blue mug with oddly shaped dice

The class should form 4 groups.
For each station, devise a sampling (not a census) experiment
that you can do in 5 minutes
to try and figure out the desired percentage.
Each group will have 7 minutes total with each station.
Use your time effectively - if you finish early, try and
redo your experiment (the more trials the better), or do another
experiment.

Take notes on your group activities and
prepare to present your work to the rest of the class. Explain your
experiments and results. Critique the problems and biases in your
sampling experiments.
